It consists of a PV module with a thin-film hydrophilic wicking evaporator and an adaptive control platform. By using the potential difference of water, the thin-film evaporator
The hydrophobic coating can eliminate dust particles using only fresh air. The high-speed wind enhances the self-cleaning process, which also increases the coated PV panel''s overall efficiency. In addition, compared with

Abstract. Photovoltaic (PV) power generation is a clean energy source, and the accumulation of ash on the surface of PV panels can lead to power loss. For polycrystalline PV panels, self-cleaning film is an economical
After UV irradiation, all samples presented superhydrophilic behaviour (angle < 5°), except uncoated glass, showing how coating applications were efficient to give superhydrophilic property to the glass. Superhydrophilic surface is promising for photovoltaic module due to its self-cleaning effect.
Superhydrophobic coatings can increase the efficiency of solar PV cells by enhancing and improving their durability. This development provides a comparable alternative to other nonrenewable or eco-unfriendly energy sources which have high efficiency.
When sunlight shines on the photovoltaic panel, part of the visible light will be reflected, and the rest will be converted and utilized. Therefore, the transparency and anti-reflection of the self-cleaning coatings applied on photovoltaic modules cannot be ignored.
For photovoltaic application, besides the self-cleaning properties, the coating should present adequate adhesion and transparency in the wavelength region 300–1800 nm.
The self-cleaning coating has attracted extensive attention in the photovoltaic industry and the scientific community because of its unique mechanism and high adaptability. Therefore, an efficient and stable self-cleaning coating is necessary to protect the cover glass on the photovoltaic panel. There are many self-cleaning phenomena in nature.
Reflected light represents uncaptured energy; therefore, decreasing the proportion of reflected light represents a promising approach for increasing the efficiency of PV panels. Textures on the front surfaces of the panels are often used to reduce the reflectance; however, it will be significant if the surfaces achieve lower reflective light.
